A user equipment (UE) receives positioning assistance data including one or more Positioning Reference Signal (PRS) resources, PRS resource sets, and TRPs, and information related to one or more Reflection Objects (ROs), such as Reconfiguration Intelligent Surfaces (RISs). A prioritization of PRS signals and/or ROs for measurement and/or reporting is based at least on the information for the one or more ROs. For example, prioritization may be determined based on whether an RO is reflecting PRS signals that will enhance positioning performance for the UE. Accuracy requirements for positioning or measurement may similarly be determined based at least in part on associate of the RO with PRS resources. Measurement of the PRS signals and/or reporting of the measurements is performed based on the prioritization of the PRS signals and/or ROs.

This application is a National Stage Application filed under 35 U.S.C. § 371 of PCT International Application Serial No. PCT/US2022/049055 entitled “POSITIONING RESOURCE MEASUREMENT AND REPORTING PRIORITIZATION BASED ON ASSOCIATED REFLECTION OBJECTS” and filed on Nov. 4, 2022, which claims the benefit of Greek application No. 20210100874, entitled “METHODS AND APPARATUS FOR POSITIONING RESOURCE MEASUREMENT AND REPORTING PRIORITIZATION BASED ON ASSOCIATED REFLECTION OBJECTS” and filed on Dec. 14, 2021, which are expressly incorporated by reference herein in their entirety.
Aspects of the disclosure relate generally to positioning for user equipment (UE), and in particular for prioritization positioning reference signal measurements and/or reporting during positioning.
Wireless communication systems have developed through various generations, including a first-generation analog wireless phone service (1G), a second-generation (2G) digital wireless phone service (including interim 2.5G networks), a third-generation (3G) high speed data, Internet-capable wireless service, and a fourth-generation (4G) service (e.g., Long-Term Evolution (LTE), WiMax). There are presently many different types of wireless communication systems in use, including cellular and personal communications service (PCS) systems. Examples of known cellular systems include the cellular Analog Advanced Mobile Phone System (AMPS), and digital cellular systems based on code division multiple access (CDMA), frequency division multiple access (FDMA), time division multiple access (TDMA), the Global System for Mobile access (GSM) variation of TDMA, etc.
The accompanying drawings are presented to aid in the description of various aspects of the disclosure and are provided solely for illustration of the aspects and not limitation thereof.
FIG. 1A illustrates an exemplary wireless communications system, according to various aspects of the disclosure.
FIG. 1B shows an architecture diagram of an NG-RAN node that includes a gNB Central Unit, a gNB Distributed Unit, and gNB Remote Unit.
Aspects of the disclosure are provided in the following description and related drawings directed to various examples provided for illustration purposes. Alternate aspects may be devised without departing from the scope of the disclosure. Additionally, well-known elements of the disclosure will not be described in detail or will be omitted so as not to obscure the relevant details of the disclosure.
The words “exemplary” and/or “example” are used herein to mean “serving as an example, instance, or illustration.” Any aspect described herein as “exemplary” and/or “example” is not necessarily to be construed as preferred or advantageous over other aspects. Likewise, the term “aspects of the disclosure” does not require that all aspects of the disclosure include the discussed feature, advantage, or mode of operation.
Those of skill in the art will appreciate that the information and signals described below may be represented using any of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols, and chips that may be referenced throughout the description below may be represented by voltages, currents, electromagnetic waves, magnetic fields or particles, optical fields or particles, or any combination thereof, depending in part on the particular application, in part on the desired design, in part on the corresponding technology, etc.
